It seems that over the weekend DTN added some fields that made their data incompatible with Tradestation and possibly other charting applications. No advance notice, no one in tech support knew anything about it, just no data. I reinstalled Tradestation and it still would not work. I thought it may be best to do a disk restore as Omega and DTN said there was no reason it would not work unless my system was at fault. Luckily eventually tech support at Omega and DTN told me that I was not the only one without data. I understand that DTN may broadcast a "fix" sometime tonight. As of 11:38 still down. A note of thanks to Omega. I tried to download my missing day of data with Historybank and was impressed as it worked perfectly. As I have not used it in a long time I was surprised they even had data for symbols like @JSN that I thought was peculiar to DTN. Chasmann
